Various chapters of the book covering water pollution, air pollution, soil pollution, noise pollution and radiation describe in details about the sources and effects of pollutants. Control measures to mitigate pollution are added at the end of each chapters. Special emphasis has been laid on topics of international and global concern such as greenhouse effect, stratospheric ozone depletion, photochemical smog, aerosols and acid rains and are discussed well. We hope that this book will satisfy the needs of undergraduate and postgraduate students of environmental biology. This book has been checked thoroughly and corrected to the best of our knowledge, however, errors and suggestions brought to our notice will be appreciated.
